摘要： The invention concerns a method for controlling the integrity of the value of a piece of navigation information delivered by a merging/consolidation device including a plurality of processing modules. Each module generates a navigation solution from measurements coming from one or a plurality of separate navigation devices, which involves defining, for each processing module, a radius of protection, corresponding to a given probability of failure. The method includes defining at least one consolidated area that encompasses protection areas centered on the solution values that are output from the processing modules and that correspond to the radii of protection defined for these modules. The radius of protection of the merging/consolidation device for the probability of failure itself is defined to correspond to the consolidated area.

摘要： The invention relates to a method for the autocalibration of an inertial rig comprising an inertial core defining a sensor reference frame, implemented in the course of at least two missions (Mn, Mn+1) each comprising the determination, on the basis of ON measurements of gyroscopes, of the orientation of the rig in a reference frame comprising the north axis (N) and the vertical axis (Up), the method comprising the implementation:—in the course of a mission (Mn), of an estimation (200) of drift errors of the gyroscopes for the orientation of the rig at least with respect to the north axis (dgyrN); and—in the course of a following mission (Mn+1), of a calculation (400) of corrections of drift errors (DXn) of the sensor reference frame (X,Y,Z), on the basis of the estimated drift errors; and—of a calculation (600) of drift errors (Xn+1), consisting in correcting drift errors (Xn) of the sensor reference frame that were calculated during the previous mission (Mn).
